isovolumetric
w =0
adiabatic
q = 0
looks like isothermal but is steep
no heat transfer
insulate the thing or really fast bc heat is reactionary, instantaneous change
isobaric
pressure same STUPID (nothing = 0)
isothermal
∆U = 0
0 = Q + W (Q and W equal and opposite)
energy came in, but equal energy out
heating → work or work → heating
